  • the top plate is a work plate.
  • the blanking plate rubs against its face lower with each movement of the drawer. This face is eroding so relatively quickly which forces you to change the upper plate each time the plate is changed shutter.
  • Such a device is provided for the replacement of refractories during casting, not between two castings. He cannot therefore allow access to the junction plate for verification and possibly change it.
  • a set of new refractories is introduced on one side of the pouring hole, while the set of used refractories is evacuated on the opposite side.
  • the introduction of refractory new must be done alternately on one side then on the other side the pouring hole, so the device requires three zones separate, namely an area for introducing new refractories, a casting zone, and a refractory evacuation zone Used. Its size is therefore at least equal to three lengths of plates.
  • the device does not describe any means for putting the refractories in place and remove them easily.
  • the subject of the present invention is a casting device and a method of implementing this device which resolve these problems.
  • the device has a guide surface substantially extending the junction surface of the orifice poured into the introduction / extraction zone, so as to ensure a pre-guiding of the fixed plate relative to the surface of junction of the pouring orifice to facilitate installation and / or removing at least the fixed plate by sliding on the junction surface.

  • the flatness of these two surfaces facilitates installation and / or removal of the fixed plate by sliding on the junction surface of the pouring orifice.
  • the junction surface of the pouring opening consists of a plate refractory. This plate is changed between two flows while the container is empty and the steel is not leaking not. It is therefore impossible for steel to enter between this junction plate and the fixed plate.
  • the guide surface should be exactly at the same level as the junction surface. But this is not mechanically achievable due to machining tolerances.
  • the level of the guide surface is therefore equal by default (i.e. within machining tolerances) at the the junction surface of the pouring orifice, a chamfer being provided to facilitate the positioning of the plate fixed on the junction surface of the pouring orifice.

  • the junction surface of the pouring opening can be consisting of a refractory plate surrounding the orifice of casting mounted on a metal support allowing to ensure rigid fixing of said refractory plate on the metallurgical container.
  • the metal support may have at least a portion of co-planar surface with the refractory plate of so as to enlarge the bearing surface of the fixed plate on the junction surface of the pouring orifice.

  • This container can be a dispatcher, or a pocket, or even, as in the example illustrated, a converter for the production of steel.
  • a drawer shutter, designated by the general reference 10 is fixed under the container. The steel in the converter is poured into a pocket 3.
  • FIG. 2 a schematic view in section of the device.
  • the steel wall 2 of the container is covered by a protective layer 4 of material refractory, for example bricks.
  • a tap hole 6 allows the metal to exit the converter.
  • the hole of this hole is delimited by an outer surface 8, flat in the example shown. This surface 8 constitutes a junction surface.
  • the drawer shutter 10 fixed under the container consists a frame 12 fixed to the outer wall 2 of the container metallurgical.
  • a frame 12 fixed to the outer wall 2 of the container metallurgical.
  • Each of the plates has one or more orifices for the passage of metal and is surrounded by a frame, 20 and 22 respectively. These two plates are enclosed in a case 24.
  • Pressure means shown schematically by the springs 26, allow to press the fixed plate 14 against the movable plate 16.
  • the drawer has two plates only, it could have more, for example three or more.
  • the housing 24 is in turn pressed by means of pressure 30 against the surface 8, which terminates the orifice of casting so that the back of the fixed plate, which has a junction surface 32 adapted to the surface 8 be applied sufficiently strongly to create a metal tightness.
  • the qualities of surfaces present are of course of sufficient quality to ensure this seal.
  • the junction surface must be sufficient great so that the leverage does not exert effort overhang. Since the means of pressure to clamp the fixed plate against each other and the moving plate are different from the pressure means to press the junction surface of the fixed plate against the junction surface of the pouring opening, it it is possible to vary the pressures per unit of surface independently of each other.
  • junction surface 8 is smaller than the fixed plate. That's why it is advantageous to provide means to facilitate the implementation place and / or remove at least the fixed plate by sliding on said plane junction surface.
  • These means are constituted by a guide surface 34. This surface is located on the side of the pouring orifice 6 through which the fixed plate must be inserted. It is located substantially in the plane of the junction surface.

  • the pressure means 26 will be described more in detail with reference to fig 4. However, it should be noted that in this embodiment the clamping means of the fixed plate against the junction surface of the orifice casting are the same as the pressure means for press the fixed plate 14 against the movable plate 16. The the same means therefore fulfill two distinct functions.
  • the fixed plate is placed in the training frame of the fixed plate 20 and the movable plate in the frame for driving the movable plate 22.
  • the rod 44 of the jack 28 is retained in a housing of the drive frame of the movable plate 22.

  • This figure shows in particular the detail of the pressure devices designated as a whole by the general reference 26. They include a spring helical 46, one end of which is supported on the frame 12 and the other on a rocker arm 48. The rocker arm transmits the action of the spring, in the opposite direction, on the movable plate. The action exerted on the movable plate is retransmitted to the fixed plate, then to the junction plate 36.

  • This lock is mounted rotatably on the frame 20 for driving the plate fixed. In a first position, shown in fig 3, it enters a housing 51 of the frame 12. In its other position it enters a housing 53 provided in the frame of the movable plate 22. In the first position it immobilizes the drive frame of the plate fixed relative to the frame and, in its second position, by relative to the drive frame of the movable plate.

  • a fixed stop 52 is provided on the frame 12.
  • the fixed plate 14 abuts against this stop 52 at the end of its introduction.
  • the latch 50 has a surface 54 constituting means for taking up play to block the fixed plate against the stop 52 via the frame drive of the fixed plate.
  • This surface 54 is by example a surface constituting a helical cam. So the fixed plate and the drive frame of the fixed plate are immobilized together without play with respect to the frame. The purpose of this provision is to prevent movement relative of the fixed plate with respect to the surface of junction. Indeed the movable plate transmits forces sharp to the fixed plate. Such efforts, which are important, tend to move the fixed plate. If this last one was not blocked, it would move by relative to the junction surface of the pouring orifice, this which would result in harmful wear of the surfaces in contact with the fixed plate and the surface of junction.

  • the fixed plate 14 is first placed inside the opening of the drive frame 20 of the fixed plate on a support surface of the frame 12 located (to tolerances machining), in the extension of the surface of junction.
  • the movable plate is then placed on the plate fixed, inside the opening of the drive frame 22 of the movable plate. There is no need to perform or connection or disconnection because the cylinder rod remains fixed, during these operations, on the drive frame of the moving plate.
  • the cylinder is then actuated to pull the assembly which penetrates laterally with respect to the orifice pouring under the locking means 50, which immobilizes the two plates without any other operation additional.
  • the fixed plate 14 is brought in and / or removed and slid under pressure means 30 prior to that the fixed plate 14 does not begin to cover the orifice container pouring.
